Arsenal have confirmed that the midfielder Samir Nasri will be out of action for a month after undergoing minor knee surgery on a meniscal injury sustained during their match against Liverpool.

Arsenal started the new Premier League campaign with an already depleted squad but managed to salvage a point at Anfield following a stoppage-time own-goal by José Reina.

Arsène Wenger must now do without the versatile Nasri – who impressed during the draw – for probably the next five games, which would include their Champions League opener on 14 September.

The club said: "Arsenal midfielder Samir Nasri will today undergo minor surgery on his knee following a meniscal injury sustained during the match against Liverpool on Sunday. Nasri, who has been in impressive form, will be out of action for a month."
